IMPROVEMENT IN COMPOUNDS .FOR USE IN CONSTRUCTING WATER-CISTERNS.

Specification forming part of Letters Patent No. 126,855, dated May 14 1872.

Specification'describing an Improved Oompound to be used in the Construction of Water- Ui'sterns, invented by DANIEL H. WEEKS, of Vassalborough, county of Kennebec, and State of Maine.

The nature of my invention consists in mixing hydraulic cement with fossil-coal, broken brick or goal-ashes, mixed with pure water, me. or stare;

To prepare my compound I take one bushel of the best quality of dnalllioqcement and mix it with two bushe s o poun e rick fossil-coal or coal-ashes and then ad one liusliel of sun or ne avel, and mix the whole mass thoroughly Eogetlier with water forming a mortar of suitable consistency, and

then apply in the usual manner.

I am aware that a mixture of cement, sand,

' and'gravel has before been used for the construction of water-cisterns; but in many sections of the country gravel is not easily obtained, and this, in part, is the object of my invention. I have also proved, by an experience of thirty-five years in constructing watercisterns, that the addition of pounded brick, fossil-coal, and coal-ashes to the ordinary mixture of cement, sand and gravel, is a great improvement, forming a substance perfectly impervious to water; that it hardens quicker in Witii esses:
